Due to 0 being falsy, this code fails to parse an int argument of 0

https://github.com/nhoffman/argparse-bash/blob/master/argparse.bash#L39

for arg in [a for a in dir(args) if not a.startswith('_')]:
    print('{}="{}";'.format(arg.upper(), getattr(args, arg) or ''))

When I run my bash script with the version argument, e.g.
parser.add_argument('--version', action='version', version='%(prog)s 1.0.0')
I get the following error:
./argparse.bash: line 60: 0.1: command not found

Cool code - What's the license on this?

Since calling python my_script.py --help return an exit code of 0, shouldn't calling bash my_script.sh --help also return an exit code of 0. Currently, it is documented in the project that an exit of code of 1 will be returned, but I think it should be 0 based on this.

If action='store_true' is set, then the variable starts True or False strings, might be a better way to do this.

Hi

I'm trying to run the example.sh script: bash /home/alu/ekushele/script/bash/conf.sh
I'm getting an error:
/home/alu/ekushele/script/bash/conf.sh: line 28: warning: here-document at line 4 delimited by end-of-file (wanted `EOF')
File "/tmp/tmp.hl53hz9h93", line 25
echo required infile: ""
^
SyntaxError: invalid syntax
: numeric argument requiredash/conf.sh: line 4: exit: 1

What can I do?

The proper thing to do would be to abandon *sh altogether, and instead use a scripting language with a proper library for defining a command line interface. Can anyone think of one?

I think that Xonsh (http://xon.sh/) might be able to do that.
